UNITED STATES JOHN J. BRIDLEB, OF SAN FRANCISCO, CALIFORNIA,

WINDOW CONSTRUCTION.

Application filed January 19, 1925. Serial No. 3,304.

To all whom it may concern:

Be it known that I, JOHN J. Blunnnn, a citizen of the United States, and resident of the city and county of San Francisco and State of California, have invented certain new and useful Improvements in Window Construction, of which the following is a specification.

The present invention relates to improve- .nents in window construction, and more particularly to those constructions embodying with the usual counter-balance upper and lower sashes means whereby these sash members may be swung about hinged points into positions within the room for the better convenience and safety-of the window cleaner.

A principal object of the invention is to provide, in a window of the upper and lower sash type, counter-balanced and adapted to be raised and lowered, means whereby the sash members may be swung into positions within the room and secured there temporaril y without necessitating the disengage ment or disarrangemcnt of counter-balances,

as a safety measure and matter of convenience to those engaged in their cleaning.

A further object of the invention is to provide a window construction of a character that will permit of the windows, where screened, being washed without necessitating the removal of the screen.

Additional objects, in a window construction of the character designated, are the provisions of anti-rattling means adapted to wedge the sash members against the easement sides, a retaining means adapted to secure the sash members in position after being swung inwardly into the room, and means enabling the sash members to be raised, lowered or swung inwardly into the room without disengagement or disarrangement of such counter balances or weights.

In the accompanying drawings, forming a part of this specification and, in which, similar characters of reference refer to like parts, throughout,

Figure 1 is a side elevation of a window construction, embodying the principles of my invention and showing the sash members in locked position and as they appear when viewed from within the room, parts being broken away to disclose one of the hinge members of the lower sash;

Figure 2 is a perspective view, showing both sash members released and swung into the room, the upper sash being drawn down close to the sill and in corresponding position to that of the lower sash member, both sash members being thus in position for washing purposes; I

Figure 3 is a horizontal sectional view, taken through the easement and upper sash member and indicated at the line 33 of Figure 1, and showing the slotted pulley stiles, the upper and lower hinge members, and the centrally hinged upper and lower sash members;

Figure 4 is a perspective detail of one of'the upper sash hinge members, showing the shank, or tongue, extension member, which extends through the pulley stile slots, and guide shoes for retaining the hinge shanks in these slots; and i Figure 5 is a perspective detail of one of the lower sash hinge members.

The present invention is supplementary to my application for windows, filed August 5, l924i, serial No. 730,176, and is intended to cover changes and refinements since made in that construction, as hereinafter set forth.

In detail, my invention is comprised of the ordinary window casement 1, including the pulley stiles 2 and 3, the sill 4 and stile header 5, of usual construction, and the upper and lower sash members 6 and 7. The sash members 6 and 7 are centrally hinged and counter balanced by means of cords 9 and 10 and counter weights 11 and 12, which is ordinary construction, except in that but one cord and weight is attached to each sash, the opposite edge of the sash being free to swing inwardly in a horizontal plane when released from the parting strips of the pulley stile, as hereinafter described,

The stiles 2 and 3 are provided with longi tudinal slots 13 and 14 extending from adjacent the sill 4 to near the stile header 5 and adapted to form guideways for the hinge member extensions of the sash hinges 1516 and 17-18, of the sash members 6 and 7 respeetivel The sash members are parted vertically, and the upper sash member 6 is comprised of panels 19 and 20 centrally hinged by means of hinges 21 and 22, and the lower member 7 of panels 23 and 24 also centrally hinged by means of hinges 25 and 26, with the sash member 6 secured to the hinges 15 and 16, and the sash member 7 secured to the hinges 17 and 18, each sash being adapted for movement up or down, or to be swung inwardly'independently of the other.

The sash hinges 15 and 16 are duplicates in construction and comprise attaching plates 27 adapted for attachment to the outer edges of the sash members, by screws, or the like, and having flanged extensions 28 forming hinge but-ts 29 and correspond ing flanged plates 30 forming hinge butts 31 and integrally formed extension plates 32, the plates 27 being of substantially L-torm, and that of the plates 30 substantially ot Z-shape, as shown in Figure The sash hinges 17 and 18 are alike, and comprise attaching plates 32 having flanged extensions ill forming hinge butts 35, and flanged plates 36 forming hinge butts 37, and integrally formed extension plates 38. The hinge butts of both sash hinges are adapted to lie flush against the inner faces of the sash members and are spaced inwardly from the edges the proper distance to allow the sash members to clear the stops 39 and 40, when swung into the room, as shown in Figure 2. The extensions 32 and 38 of the sash hinges extend through the slots 13 and 15': of the stiles 2 and 3 and are held in place by means o1 runners, or guides, 41 and -12, slotted at 13 and lei: to receive said extensions and are held in place by means ol keys, or the like fasteners, l5 and "16.

The sash members are adapted to slide freely and carry their respective sash hinges 15-40 and 1718, said hinges being brought into play only when the sash members are broken vertically and centrally at their parting lines.

The sash members are each provided with a small hook, 517 and 48, adapted to engage pins, or stops, 1-9 and 50, positioned upon the inside top faces thereof and opposite the hinges 21 and 25, to hold the panels l9-20 and 28-2lin a common plane and abutting end to end, when in closed position. An ordinary eccentric window lock 51 is attached to the upper edge of the sash 7 and serves to maintain the several parts constituting the members (5 and 7 in locked relation.

The inner hinged abutting edges of the sash members are fitted together, tongue and-groove fashion, as indicated at 52 and 53, to form weather and water-tight joints.

The sash members may be raised and lowered in the ordinary manner and, when is desired to swingthem into the room for purpose 0t cleaning, the hook 48 on the lower sash member 7 is released and it is broken inwardly upon its hinges 25 and 26, thereby allowing its tree edge to swing clear of the stop 29 and to be swung inwardly upon its sash hinges 17 and 18 to the position shown in Figure 2. The upper sash (3 may be released by pulling it below the stile header and breaking it inwardly upon its hinges 21 and 22, to clear the stop all, and, i1" desired, it may be drawn down even with the lower sash, as shown in Figure 2.

Having thus described my invention, I claim, and desire to secure by Letters-1 Patent:

1. In a window construction, the combination of a casement and pulley stiles, elongated guide-slots in said pulley stiles, upper and lower sash members slidably mounted between the pulley stiles and com prised, respectively, of a pair of centrally hingzjed panels provided with tongue and groove abutting edges, eounter-weiglits for each of said sash members, sash hinge-members secured to the edges ot said sash members and having ollset butts and extensions adapted to engage in said guide-slots, guideshoes adapted to maintain said hinges in slidable relation with the easement stiles, keys adapted to extend through said 02:- tensions and maintain said shoes in place, and hooks mounted at the parting lines of said hinged panels opposite the hingeanem' bers thereof and adapted to maintain said panels in a common plane and, when released, to allow said sash-member panels to break inwardly at their parting lines and to swing upon the sash-member hinges and clear of the easement parting strips.

2. In a window construction, the combination of a casement having pulley stiles, elongated guide-slots in said pulley stiles, upper and lower counterbalanced sash-menibers having sash-hinges secured in pairs at opposite side edges and provided with offset butts and extensions and adapted to engage said slots and slide up and down with said sash-members, said sash members being comprised of centrally hinged panels provided with tongue and groove abutting edges and tree at their opposite edges and adapted to swing horizontally in a common plane in opposite directions into the room, thereby clearing the easement parting strips, and fastening means positioned opposite the hinged edges 0t said panels and adapted to maintain said panels end-to-end in a com mon plane when closed.
